Adjustments for Better Print Quality Adjusting Line Length To ensure that lines in CAD drawings are printed at exactly the right length, use Adjust Length to adjust the amount that paper is advanced. There are two options in Adjust Length : AdjustmentPrint and Change Settings. • AdjustmentPrint After a test pattern is printed, you will measure the discrepancy based on the results of printing. • Change Settings No test pattern is printed.

Choose the mode that suits your particular printing application. • A:High This setting is applied when Highest or High is selected in Print Quality in the printer driver. • B:Standard/Draft This setting is applied when Standard or Fast is selected in Print Quality in the printer driver. • Always check the Adj.
